INN-JOINT.

SPECIFICATION forming. part of Letters Patent No. 729,556,dated June 2, 1903.

' Application filed November 12, 1902. SerialNo. 130,951- (No model.)

' To all whom it vncty concern:

Be it known that I, GEORGE W. DOVER, a citizen of the United States, residing at Oranston, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Pin-Joints, of which the following is a specification.

the construction hereinafter detailed, and

shown in the drawings, wherein-- Figure 1 is a side elevation of my new pinjoint; Fig. 2, a similar view of the same, showing the housing in vertical central section; Fig. 3, a detail view of the housing in original form, and Fig. 4, a view of the latter after being pinched to final position, said view being takenon line m x of Fig. 2.

Similar reference-letters refer to like I parts in the above views.

My improvement isiembodied as follows:

To the front or bodyA of a brooch or similar ornament is soldered at its lower edge a semielliptical-shaped housing B, having parallel vertical sides or walls a and fiat base (1, as in great- Fig. 3. This housing is soldered along itsflat base d to the body or plate A. It will be seen that this flattened formation furnishes a complete and stable contact and preserves the equilibrium of the housing during the soldering. After the soldering operation the pin-tongue is inserted within the housing B. The pin portion 1) is substantially straight; but the blunt end 0 is crooked or folded back into the vertical plane, of the pin portion and forms a foot which preferably terminates some distance Within the housing; but it may, if preferred, be arranged flush with the same. After insertion of the pin tongue, as described, the side walls a of the housing B are pressed together by a foot-press or other con- 'venient means into the form shown in Fig. 4,

whereby the crook of the pin-tongue is held rigidly against displacement.

It will be noted that by soldering the bottom of the housing to the brooch no portion of the pin member is exposed to the flame.

Having thus described my invention,what I claim is- In a pin, the combination with the plate of a semi-elliptical housing, with contacting side walls, apd a pin-tongue provided with a crooked blunt end, said end being held in position by the compression of said walls.

In testimony whereof I have affixed my signature in presence of two witnesses.

GEORGE W. DOVER.
